Videostroboscopy is a procedure used to assess the structure and movement of the vocal cords, and to examine the surrounding structures in the larynx and throat. The procedure requires use of a scope, camera, recording device, TV monitor, microphone, and strobe light. A rigid scope is inserted into the mouth (not down the throat) and images of the vocal fold vibration are recorded. A flexible scope may be inserted into the nasal cavity instead if a patient’s gag response is too strong or a more comprehensive exam is needed.
Who performs the exam?
Videostroboscopy may be performed by either an otolaryngologist (ear, nose, and throat doctor) or a speech-language pathologist.
Why is videostroboscopy performed?
Videostroboscopy is performed to assess the structure and movement of the vocal cords, and to examine surrounding muscles and tissues in the larynx. Patients are frequently referred for this type of exam due to hoarseness or inadequate voice quality.
How is a videostroboscopy performed?
- You will be asked to complete a brief recording of your voice to assess vocal quality.
- A topical anesthetic may be applied to the back of your mouth for your comfort during the exam.
- While holding on to the tip of your tongue with gauze, the speech-language pathologist or physician will insert a rigid scope towards the back of your mouth (No scopes are inserted into or down your throat).
- You will be asked to perform simple vocal tasks to assess the condition of the larynx and movement of the vocal cords. The scope will remain in your mouth for 2-3 minutes.
- The speech-language pathologist will describe the recorded images of your larynx and vocal cords. The physician will provide a diagnosis and make recommendations regarding your plan of care.
How long does the exam take?
Your entire appointment may last 20-30 minutes; however, the scope is only in your mouth for approximately 2-3 minutes.
What do I need to do to prepare for the exam?
There is no preparation needed for videostroboscopy. You may eat and drink prior to the exam.
